Develop two test type questions open ended not multiple choi

Develop two test type questions (open ended not multiple choice) using either the Empirical Rule or Chebyshev\'s Theorem.  

Examples:

The median income of all Americans in 2010 is $33,810 with a standard deviation of $5,100. Use Chebyshev\'s Theorem to find an interval in which at least 75% of the Americans median income will lie?

The sample mean of monthly car payments in New York is $500 with a standard deviation of $50. What percent of car payments falls between $400 and $600?

Solution

1)

the sample mean of hours of work in EEUU is 8 hours with a stnadard deviation of 1.5 hours

What percent of hours of work fall between 7 and 9 ?

2)

The mean income of Subway is $50,000 with SD of $2500

Use Chebyshev\'s Theorem to find an interval in which at least 75% of the mean income will lie?
